Title

Sodium Diffusion in Glass: III, Sodium Metaphosphate Glass

Abstract

Isotope-effect measurements for 22Na/24Na diffusion were used to investigate the diffusion mechanism of Na in a sodium metaphosphate glass. A vacancy-interstitialcy multiple mechanism was in best agreement with the experimental data. Near the transition temperature Na+ diffusion occurs primarily by the vacancy mechanism, whereas with decreasing temperature an increasing fraction of Na- diffuses by a noncolinear interstitialcy mechanism.
